i have been trying some different things with my pedals and have set up them some ways and have not been getting a signal sometimes..then i got a good signal another way
what is the difference between the two: input/output and send/return
Anyway; input is where your guitar goes in output is where you plug your amp in. Send goes to the input of the pedals return comes from the output of your pedals
eventually you can choose to put modulation effects such as delay between the output and your amp and not in the send/return loop.
Mesjoggah nails it. Its not exactly rocket science.
